After months of chatter, Google formally introduced its 'Project Glass' with a brief concept video meant to solicit ideas for what people would like to see such a gizmo do. Google is keeping details of the project secret, with most of the work being done in the company's mysterious Google[x] labs in Mountain View, California.

Google has not shared a release date or price for its Glasses, but it has previously stressed that the product will not be available this year.
